The integration of GPS functionality into mobile phones has had traditional satnav manufacturers such as Garmin working even harder at creating “must have” features which will give their products a point-of-difference. There's also no better way to a golfer's heart than the promise of a reduced handicap, so Garmin's new waterproof Approach G3 (2.6 inch screen) and G5 (3.0 inch screen) should prove popular. Both come preloaded with 1,250 courses and by capturing intimate detail of every round, they will aid in club selection by detailing distance to the pin or the ideal position to land the ideal approach shot. As you'll already have assigned a club to each shot, so you'll know your average yardage per club, the distance and position of every bunker.
